[PATCH] mac80211: do not set IEEE80211_STA_DISABLE_HE for NL80211_BAND_2GHZ

[Wen Gong]

VHT is not support for NL80211_BAND_2GHZ, but HE is support for it, so
it should not set IEEE80211_STA_DISABLE_HE for NL80211_BAND_2GHZ if it
does not support VHT.

When connec to AP with NL80211_BAND_2GHZ, it does not support VHT, then
it failed for HE and connected with HT mode. After this patch, it connected
with HE mode for NL80211_BAND_2GHZ with a HE mode 11AX AP.

Fixes: 57fa5e85d53ce51 ("mac80211: determine chandef from HE 6 GHz operation")
